Subject: Address Resolution

Whether one uses PPP (with LQM negotiated off), or not, there is
a question about address resolution.  Several people have suggested
that the multi-cast solutions are too expensive in bandwidth and
excessive bits transmitted.  This may well be true.  However,  I
would sincerely hope that we are not going to insist on the full
overhead of X.500 when we need to resolve an address?

I would suggest that a server aimed specifically at the lower layer
service, such as an ES-IS server as envisioned by ISO, might be a
more effective solution to this problem.  

I personally rather like the idea of a multi-cast address which such
servers will listen to.  Then a box will send to that address when it
starts up, and not the responses.  Then it can use those address for
address resolution requests.  This should simplify customer configuration.
